I have a problem with OpenOCD and GDB. Debugging works fine if I erase at least the first sector of the lpc2148 – I use telnet for that (flash\_erase\_sector 0 0 0). So if I start a debugging session in Eclipse everything works fine. But if I stop the session and try to restart a new one I get this error. ```auto Open On-Chip Debugger 0.3.0-in-development (2009-08-19-10:19) svn:2596 $URL: svn://svn.berlios.de/openocd/trunk/src/openocd.c $ For bug reports, read http://svn.berlios.de/svnroot/repos/openocd/trunk/BUGS 30 kHz jtag_nsrst_delay: 200 jtag_ntrst_delay: 200 Info : device: 4 "2232C" Info : deviceID: 67358712 Info : SerialNumber: 32OZPDQCA Info : Description: Amontec JTAGkey A Info : clock speed 30 kHz Info : JTAG tap: lpc2148.cpu tap/device found: 0x4f1f0f0f (mfg: 0x787, part: 0xf1f0, ver: 0x4) Info : JTAG Tap/device matched target state: halted target halted in ARM state due to breakpoint, current mode: Supervisor cpsr: 0x60000093 pc: 0x40000070 30 kHz Info : JTAG tap: lpc2148.cpu tap/device found: 0x4f1f0f0f (mfg: 0x787, part: 0xf1f0, ver: 0x4) Info : JTAG Tap/device matched Warn : srst pulls trst - can not reset into halted mode.

Warning: Cannot insert hardware breakpoint 1.

Sometimes I must halt the target before the erase command works. I use the latest Version of OpenOCD with FTDI-Lib and the latest Eclipse and Zylin tools. These are my gdb init commands: ```auto target remote localhost:3333 monitor poll monitor reset init monitor sleep 500 monitor mww 0xE01FC040 0x0001 monitor mdw 0xE01FC040 # needed for gdb 6.8 and higher set mem inaccessible-by-default off monitor flash probe 0 load break main continue ``` I do not know what´s wrong. thanks mgiaco ---

So now it works but i need to erase every time i start a session but why? ```auto target remote localhost:3333 monitor poll monitor halt monitor sleep 500 monitor flash_erase_sector 0 0 0 monitor soft_reset_halt monitor reset init monitor sleep 500 monitor mww 0xE01FC040 0x0001 monitor mdw 0xE01FC040 # needed for gdb 6.8 and higher set mem inaccessible-by-default off monitor flash probe 0 load break main continue ``` ---

Try this: target remote localhost:3333 monitor reset halt load 4/3!! ---

Hello Freddie, ```auto target remote localhost:3333 loop () at main/startup/ex11_start.S:210 210 loop: b loop Current language: auto; currently asm monitor reset halt monitor reset init monitor sleep 500 monitor mww 0xE01FC040 0x0001 monitor mdw 0xE01FC040 set mem inaccessible-by-default off load Error erasing flash with vFlashErase packet Breakpoint 1 at 0x190: file main/src/main.c, line 54. break main Note: automatically using hardware breakpoints for read-only addresses. continue Warning: Cannot insert hardware breakpoint 1.

I’ve proposed this set: target remote localhost:3333 monitor reset halt load You entered: target remote localhost:3333 monitor reset halt monitor reset init monitor sleep 500 monitor mww 0xE01FC040 0x0001 monitor mdw 0xE01FC040 set mem inaccessible-by-default off load break main continue You see any difference? 4/3!! ---

To enable flash programming via load in gdb you need to make sure valid flash banks are configured: flash bank lpc2000 0x0 0x7d000 0 0 0 lpc2000\_v2 14765 calc\_checksum and also a working area to speed things up - look at the default lpc2148 cfg for an example. What will happen when gdb connects openocd will send the memory map to gdb. Then when you use the gdb load cmd it will erase the flash for you and then write the new flash. The following cmds are not required, they will be done automatically: set mem inaccessible-by-default off monitor flash probe 0 [http://openocd.berlios.de/doc/html/GDB- … nd-OpenOCD](http://openocd.berlios.de/doc/html/GDB-and-OpenOCD.html#GDB-and-OpenOCD) may provide more info. If you are still getting trouble then attach a full openocd debug log -d3. I do not use lpc’s, so these guidelines are general. Cheers Spen ---

Hello Freddie, Okay so i try your commands and i get these errors. ```auto target remote localhost:3333 0x0000033c in main () at main/src/main.c:226 226 if (timer_cnt0 > counter) { monitor reset halt load Error erasing flash with vFlashErase packet ``` @ntfreak thx i will have a look at that. thx mgiaco ---

What’s the output of OpenOCD when you issue those commands? You can also try this method: To find out what’s wrong start OpenOCD as usuall and open Command Prompt (cmd) and type: telnet localhost 4444 this will connect you to OpenOCD via telnet. Now you can try commands like: reset halt poll and post the output (of telnet and of OpenOCD in the other command prompt) here. You can also try to flash the chip via telnet with flash write\_image … (the details in the User’s Guide of OpenOCD) 4/3!! ---

Even I am facing a similar problem with wriggler. The microcontroller is not halted after reset.

I have checked the nrst - Pin 15 - of jtag header does go low. Anything else I can try ? Thanks Rakesh ---

Hello, I am getting the same error of Target not halted. Also d monitor command error pops up and if I remove all the monitor commands,I still get d msg “Error: Launching main.elf file”… Anyone please tell me the solution of at least one of these problems… ---
